9 Wonderful 100th Birthday Invitations for Your Loved One

A loved one is turning the big 100, and it’s time to celebrate! Alongside planning an incredible celebration for their special day, choosing the right 100th birthday invitations can bring out a smile well ahead of the big moment itself.
If you’re looking for the kind of birthday invites that match this momentous occasion, you’re in the right place. Let’s explore how to create and send memorable 100th birthday invites the easy way, without compromising on style.
How to Create and Send Incredible 100th Birthday Invitations
It’s the milestone birthday that tops all milestone birthdays, and that deserves special attention in all areas of the celebration — including the design and wording of your invites. Here’s how to plan, prepare, and send out 100th birthday invitations for a beloved family member or friend.
1. Choose a Theme
We love birthday party invites with a theme, and it’s a wonderful way to get people excited about the special occasion. If you have a 100th birthday party idea or theme in mind, look for a design that matches — whether it’s an afternoon tea party, elegant dinner party, or a relaxed garden party.
If you don’t have a specific party theme, don’t worry. There are plenty of adult birthday party invitations out there that can bring some style to the occasion without following a particular theme. Great examples of this include florals, the color gold, vintage, or an interest-based design like fishing, golf, or art.
2. Find the Perfect Design

Design: Signature Greenvelope
With a theme or overall style in mind, it’s time for the fun part — finding the ideal 100th birthday party invitations for that special someone. At Greenvelope, we have hundreds of stunning designs that cover just about any interest, color palette, and aesthetic you can think of.
Our collection of online invitations is filled with designs from talented artists and creators, giving you a wide range of choice. You can explore high-quality invite designs (like this milestone collage birthday invite) and opt for something luxurious in style, without worrying about custom design costs, finding cardstock for printable invites, or shipping costs.
3. Customize the Birthday Party Invitations
Once you’ve found a design that works for your loved one, it’s time to get customizing! Our easy-to-use birthday invitation template editor allows you to experiment with layout, fonts, colors, and more — giving you an easy way to personalize the designs.
It’s not just the adult birthday celebration invite you can customize, either. You can now choose from a variety of different digital envelope options, so you can find something more grand than a plain white envelope.
As all our designs are customizable, you can also explore beyond designated 100th birthday invitations. Go ahead and see if you can find a design you love for a 30th birthday, 70th birthday, or 90th birthday invitation — or even a baby shower invitation or greeting card. With a few simple changes, you can transform any invite into a memorably 100th birthday invitation.
4. Add Your Own Personal Wording
Personalizing the invite’s design is a great way to give it that bespoke feel, but you can also go one step further by adding custom wording to your birthday invitation cards.
Some fun wording, a poem, or a lovely story about the guest of honor’s adventures is a sweet way to honor their big day. Many of our designs have plenty of space on them to add your own special wording, whether that’s right on the front or on the reverse.
Spend some time thinking about what to say, then fill in your invite template with your chosen wording. Here are some ideas to get you started:
- [Name]’s big birthday is coming up, and we’d love you to celebrate alongside us!
- Join us at [Venue] as we bring out the golden balloons and champagne to toast [Name]’s 100th birthday.
- We’re celebrating [Name] turning 100 in the only way they’d allow — with a BBQ in the backyard!
- In honor of [Name]’s big birthday, we’re inviting you to join us for afternoon tea at [Venue]. Dress in your best, and bring all your favorite stories and memories.
Use these birthday invitation wording ideas as they are, or customize them even further.
5. Send Out the 100th Birthday Invitations
Once you’re happy with your final invitations, it’s time to send them out to your loved one’s guest list. Sending invites for a big moment like this is easier than ever with Greenvelope.
All you need is a recipient’s email address or phone number, so they can receive an email or SMS version of the invite. Upload your guest list, and either send immediately or schedule for a future date.
6. Manage RSVPs the Easy Way
It’s not just sending invites that’s easier online — coordinating your guest list and managing RSVPs becomes simpler too. Instead of keeping track of who’s coming and who isn’t on a list or spreadsheet, everything is recorded in your Greenvelope dashboard.
Guests can RSVP straight from the invitation, so they’re less likely to forget how or when they need to reply. If you do need to send anyone a reminder, this is easy too with automated followups. Spend more time planning the 100th birthday party of their dreams, instead of chasing guest responses.
